RECEIVER SEPARATOR.

Applicationv filed May 4,

Broadly considered, the invention comprises a pressure drum having an inlet and an outlet at the top, in combination with a centrifugal purifying device positioned within the drum at said outlet.

The invention also comprises certain valuable details of construction and specific combinations of parts, all as hereinafter described.

The invention will be readily understood on reference to the drawings that form part of this specification; in which Fig. 1 is a vertical section of a receiver separator embodying my invention; Fig. 2 illustrates a modified form of the invention; Fig. 3 is a section on the line 33 of Fig. 1; Fig. 4: is a horizontal section on the line 44 of Fig. 1; Fig. 5 is a section on the line 55 of Fig. 1; and Fig. 6 is like unto Fig. 4: but shows a different tuyere blading.

The pressure drum comprises the cylindrical shell 2, the top" head 3, and the bottom head 4. One of these heads, or the side of the shell, should contain a man-h ole through which the drum may beentered.

Thepressure fluid may enter the drum at either of the'openings marked a. It will be noted that whichever inlet is selected, it is found near, or at the top of the drum. The pressure fluid leaves the drum through the outlet b.-

The fluid with its burden of impurities freely enters the drum and immediately dcposits the-greater partof its burden in the lower part of therdrum.- But the exit of the fluid from the drum is neither free norunob- *structed for at the outlet b I interpose a centrifugal fluid purifying device or separat- ,ing unit 0 through which the fluid must pass to reach the outlet of the drum and which device or unit ha the effect of depriving the fluid of the remainder of the impurities. According to design these remaining impurities are either returned to the bottom of the drum or dischargei-nto a suitable exter- 1925. Serial No, 27,848.

nal trap (not shown). The drum has a drain 6! for emptying it, as by means of an automatic trap (not shown). In both forms of this separator the butlet pipe I) occupies the center of the drum, rises nearly to the top thereof and converts the lower part of the drum into a collecting pocket 6.

3 Referring to Fig. 1 it will be seen that the auxiliary centrifugal separating device 0 is placed upon the top of the pipe 6 at a point above the level of the inlet a. In that position it is effectively hooded from the direct blast of the inflowing steam and impurities and most of the impurities are thrown down into the bottom of the drum before the fluid reaches the separator 0. The separative device 0 is joined to the outlet. proper b by a collar 6. It comprises the member 7 containing the annular race 7, and the multiple tangential tuyre member or ring 8. The internal diameter of the 'ring 8 is somewhat larger than that of the whirling body within the ring 8 and the race 7 By reason of this whirling motion the heavier impurities are centrifugally separated in the tuyere ring and moving downward are expansively separated in the race.

From thence the impurities are discharged through the tangential nozzle 7 going back to the bottom of the drum through a pipe 9, as-shown in Fig. 2, or being externally discharged through an extension 9 of that pipe as shown in Fig. 1. If the internal delivery, 9, is employed the drain pipe d should extend far enough into the drumto provide ,a water seal for the lower end of the pipe 9. In the above described, manner the impurities are removed from the region of the outlet 6, b and the purified fluid whirls away through that opening.

The top of the drum shown in Fig. 1 is provided with a man-hole and removable plate so that the separating unit a is readily accessible. I take advantage of this situation-to make the tuyere end 8 adjustable, the same having a threaded .stem 8 which is held in the top member or spider 8 By this means the size'and volumetric capacity of the tuyeres a may be varied to suit the volume of fluid supplied through the inlet,

.with obvious advantage in the centrifugal operation of the unit.

The separator of Fig. 2 isadaptcd to receive the fluid through its top opening a.

The only other difference of special note is inthe tuyere top 8 which is fixed and against the Wall or shell of the drum, and

thus prevent the slugging or overloading of the auxiliary centrifugal separator.

Having thus described my invention I claim as new and'desire to secure by Letters Patent 1. The herein described separator comprising a vertical drum having an inlet in its upper part, in combination with an outlet pipe leading from the upper part'of the drum, a volumetrically adjustable and selfcontained centrifugal separating unit fixed on the top of said pipe and forming the avenue through which the fluid must pass to reach said pipe. v

2. The herein described separator comprising a vertical drum having a fluid inlet in its upper part, in combination with an outlet pipe positioned vertically in said drum and leading from the upper partthere of, and a self-contained centrifugal separating unit fixed upon and supported by the upper end 'of said outlet pipe and forming the avenue through which the fluid must pass to reach said pipe a'ndescape from the drum. y

In testimony whereof I have hereunto set my hand this 30th day of April, A. D. 1925. y r
